Horotiu railway station was a station on the North Island Main Trunk in New Zealand serving Horotiu. It was a 'flag station', originally 3 mi (4.8 km) north of Te Rapa and 4 mi (6.4 km) south of Ngāruawāhia and named Pukete. The station was moved just over a mile to the north in 1880, to be 76 mi (122 km) from Auckland. It seems no explanation was given for the controversial move. The station changed its name from Pukete to Horotiu on 23 June 1907.Traffic remained light, amounting to £49 in 1901. It was converted to a switch-out station in 1909, equipped with distant signals in 1916, when the AFFCO sidings opened, and had other alterations to signalling and interlocking in 1934, with extension of automatic signalling from Mercer to Frankton. In 1930 Frankton to Horotiu (6 mi 55 ch (10.8 km)) was double tracked, with automatic signalling also extended 34 mi 72 ch (56.2 km) to Mercer. Horotiu's power interlocking was the first automatic operation of main line points in the country, replacing home and distant signals, Wood's locks (a single key for signal and facing points, named after S P Woods of McKenzie and Holland) and the tablet station. The 3 mi 54 ch (5.9 km) north to Ngāruawāhia was double track from 5 December 1937.

Te Rapa cogeneration

The Te Rapa cogeneration plant is a 44 MW cogeneration plant owned and operated by Contact Energy. It is located at the Fonterra dairy factory, at Te Rapa near Hamilton in New Zealand, and was commissioned in 1999.The construction of the plant came as part of a wider upgrade to the dairy factory proposed in 1997. The original capacity applied for under the Resource Management Act was 150 MW, but there was opposition from Greenpeace about the carbon dioxide emissions and Tainui about pollution of the Waikato River; Subsequently the planned capacity was reduced to 45 MW and the change was announced at an Environment Court prehearing. The Waikato Times reported that “Greenpeace was pleased [with the change] but said even the smaller plant would pump out 100,000 tonnes of carbon dioxide”.The plant is based on a gas turbine (a GE frame 6B) that can produce up to 44 MW of electricity. Hot exhaust gases from the turbine are ducted to a heat recovery steam generator (HRSG) to raise steam. The HRSG has duct burners to increase steam output, which can be up to 180 tons of steam per hour.The cogeneration plant is designed for flexible operation, and can provide electricity to the dairy factory, export electricity to the local network or import electricity for use in the dairy factory. A common operating mode is 30 MW of electricity exported and 15 MW plus 120 tons per hour of steam provided to the dairy factory.A 127 MW gas/diesel fired auxiliary boiler is used when the cogeneration plant is not in operation.Fonterra has been authorised by the Waikato Regional Council to install and commission an alternative combustion plant if the co-generation plant ceases to be available.
